Use this detailed guide to evaluate the advantages and disadvantages of investing in a used air compressor system
If you choose an industrial air compressor that meets your needs, you may want to consider choosing a used compressor, as an initial purchase is usually cheaper than investing in a new engine. However, the air compressor systems used can present many unique problems. Therefore, it is important to know about the possible advantages and disadvantages of a new and used
air compressor before making a decision. We divide it into:
New air compressor
it is almost always better to invest in a new air compressor. Although the initial cost of a new industrial compressor can be high, it can be an effective investment. The new compressor is guaranteed longer life, unworn pipes and filters, and higher energy efficiency – because air leaks are less likely to occur. While many are concerned about energy costs and inefficiencies, some best practices can be used to maximize the overall efficiency of your compressor and ensure that it provides a consistently high return on investment. These include leak testing, in-depth maintenance assessments, and audits, system pressure reduction, use of part load control, use of outdoor air intake as required. lost heat energy and use it to heat air or water. Finally, applying these energy-saving practices to a new compressor can increase the cost and energy efficiency of your machine and increase the sustainable value of your business.
Situations
Although a new compressor is always preferred, there are situations where it makes sense to buy a used engine. If you have access to a reputable dealer, you may want to consider purchasing a used air compressor as a temporary solution to meet your business needs. Here are some of the key considerations when buying a used industrial compressor system.
1. How much air do you need
And at what pressure? If your business needs consistently high performance and high PSI, it’s probably worth investing in a used tank compressor with a relatively large tank that can supply more compressed air at higher pressures. Although larger and more expensive than a small motor, a large compressor is perfectly energy efficient.
2. What tools do you use?
A large tank compressor is also a wise choice if your company operates pneumatic equipment such as electric drills or paint guns, as large compressors produce solid but short batches. output while allowing high PSI. On the other hand, small compressors usually cannot deliver such high pressure, but offer a constant flow of light air pressure, which may be a better option for companies that do not operate pneumatic equipment. But only require air cleaning. It meets strict, regulations. Small compressor systems can also ideal for fast production applications.
3. How powerful is your air compressor?
It is always best to overestimate the performance you need to perform operations. Other experts recommend an overestimation of approximately 40%. Often, as the volume of air in the product increases, the maximum pressure decreases. This reflects in the compressed air produced in cubic feet per minute (CFM) and in the PSI at discharge. It would be good to evaluate the standard cubic feet per minute (SCFM) of the compressor. Which is the industry standard. Measured at 68 degrees Fahrenheit at sea level and at 35% humidity. Understanding the SCFM compressor can help you make more informed. Decisions about the engine’s ability to meet the performance requirements of your equipment or applications.
4. Do you need a lubricated or oil-free air compressor?
Oil-free motors do not require much maintenance and can be smoother and more versatile than oil-lubricated air compressor systems. However, it is stronger and subject to more regular wear, which can reduce engine stability. On the other hand, oil-lubricated compressors are quieter than oil-free compressors because lubrication reduces friction and thus often reduces noise. Since they endure less frictional wear, lubricated compressors have the added benefit of higher energy efficiency and increased longevity. They tend to be the best option for applications requiring consistent airflow.
Lubricated compressors
While lubricated compressors are more durable, they require careful, regular maintenance, and run the risk of ‘misting’ in the long-run, which may pose problems for highly sensitive applications as it leads to oil-infused, or contaminated, air. However, thanks to a number of filtration innovations. Such as the Absolute Zero Oil-Free Air System, an add-on filter can be installed on any lubricated compressor to enable it to produce oil-free air that meets ISO 8573-1:2010 Class 1 and Class 0 purity standards.
5. How much wear is used on the used air compressor?
If you are buying a type of used air compressor, be sure to buy from a reputable dealer who can provide accurate and up-to-date records of engine use, and make sure you know whether it used or not being used. – which can cause great damage to many internal parts. Ask as many questions as possible and always make sure your machine meets federal, state and industry requirements.
The pneumatic impact wrench requires a specific air compressor with a minimum size to operate. But how do you find the right air compressor for a particular key? In this article, I will try my best to help you go through this surprisingly complicated process by telling you what you need to know about air compressors.
What size air compressor do you need for an impact gun?
You usually need an air compressor with 4 to 5 CFM @ 90 PSI to operate a 1/2 inch wrench. I also recommend that you buy a 20-gallon compressor to avoid delays between tasks. See the CFM card at the end of this guide for additional sizes.
Let me now explain why you need this minimum CFM and tank size.
What air pressure does the key need?
Air compressors measured. At least in part, by the air pressure (PSI) they produce. And by the air flow rate (CFM). Even if you don’t know air compressors. You can guess why air pressure is important. The higher the air pressure, the more powerful the device. Equally important is the amount of air that flows. This raises the question of what air pressure and CFM you need for your particular wrench. The answer to this question will depend a lot on the size of key you use. The bigger the key, the more air you need. There is no one-size-fits-all guide for any air tool. What size air compressor do I need for the key? Although air pressure is important, it is not the only way to evaluate an air compressor. You should also consider the size of the air compressor tank.
Are all air compressors the same?
Not all air compressors are the same. In addition to tank size, performance, and PSI ratings, they both look and work the same. However, many users do not realize. That there more important differences than can see with the naked eye. Especially with regard to the compressor pumps themselves.
What is the main purpose of the compressor?
The purpose of the compressor is to circulate the refrigerant in the system under pressure, concentrating the heat contained in it. In the compressor, the low-pressure gas converts into a high-pressure gas.
